3 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
4 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
5 equal (respectively) to the argument key, not all cells that are
6 eq, eqv, or equal to the first cell with the argument key. Thanks
7 to Neil Jerram!

11 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
12 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
13 SCM values appropriately.
14
15 * modules.c (scm_standard_eval_closure): Don't pass an inum to
16 scm_makcclo, but rather a long value.

19
20 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
21 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
22 Thanks to Han-Wen Nienhuys for the bug report.

37
38 * gc.c (scm_done_free): new.
39 expanded comments about scm_done_malloc.
40
41 * gc.h: added prototype for scm_done_free
42

DH		 432000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
44
45 * gc.h (scm_take_stdin): Removed.
46
47 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
48 scm_assert_cell_valid to allow extensions to the checking
49 functionality without need to recompile everything.
50
51 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
52 Added as conditionally compiled functions for the case that
53 SCM_DEBUG_CELL_ACCESSES is enabled.
54
55 * gc.c (debug_cells_p): Added to indicate whether compile-time
56 included cell access debugging is run-time enabled.
57
58 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
59 being executed. Intended to be used instead of scm_gc_heap_lock
60 at most places.
61
62 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
63 instead of scm_gc_heap_lock.
64
65 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
66
67 * gc.c (scm_mark_locations): Don't mark free cells.
68
69 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
70 SCM_FREEP.

74 * gc.c (scm_mark_locations): Minimized some variable scopes and
75 simplified the code a bit.

DH		 772000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
78
79 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
80 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
81 should not be accessed via SCM_C[AD]R. Further, using dedicated
82 macros to access free cells allows all other cell accessing macros
83 to treat acesses to free cells as errors, thus enabling better
84 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
85 replace SCM_FREEP some time.
86
87 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
88 free_list_length, scm_check_freelist, scm_debug_newcell,
89 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
90 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
91 cell accessors when accessing free cells.
92
f706a58b
DH		 932000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
94
95 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
96 object as const in order to make the compiler warn about code like
97 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
98 should be used.
99
100 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
101 as an address to a non-const object, since these macros are used
102 to allow direct write access to objects.

DH		 1042000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
105
106 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
107 given hash table has no slots.

DH		 1092000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
110
b6efc951
DH		 111 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
112 to react to malloc failures in a context dependent way.
113
114 (scm_check_freelist): No need to flush streams before abort().
115
116 (scm_gc_for_newcell): Try to allocate new memory in three phases:
117 grow heap if preferred, if still no memory available collect
118 garbage, if still no memory available grow heap.
119
120 (heap_segment_table_size): Added to always reflect the actual
121 size of the heap segment table, because scm_n_heap_segs may differ
122 from the heap segment table size.
123
124 (alloc_some_heap): In case of malloc failure, react according to
125 the new policy_on_error parameter (either return to caller or
126 abort immediately). Further, keep heap_segment_table_size up to
127 date.
128
129 (scm_init_storage): Initialize heap_segment_table_size.
130
1312000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
132
133 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
a6c12a04
DH		 134 the hint.

DH		 1362000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>

138 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
139 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
140 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
141 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
142 symbols.
143
144 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
145 and SCM_NALLOC, but as a deprecated feature.

c7387918
DH		 1542000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
155
156 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
157 failed attempt to get additional memory from the system.
158
159 (scm_gc_for_newcell): Changed the control structure to make the
160 behaviour explicit for the case that gc is not able to free any
161 cells.
162

DH		 1632000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
164
165 * __scm.h (SCM_OUTOFRANGE): Removed.
166
167 * error.c (scm_wta): Removed sick dispatch code for range
168 errors. (More sick dispatches still to be removed.)
169
170 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
171 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
172 value is non-negative. Use scm_out_of_range to signal range
173 errors.
174
175 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
176 signal range errors.
177
178 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
179 error reporting (now uses original input parameter to report wrong
180 type argument errors). Use SCM_OUT_OF_RANGE to report range
181 errors and SCM_WRONG_TYPE_ARG to report type errors.
182
183 * strings.c (scm_substring): Make range checks for negative
184 values explicit (former behaviour relied on an implicit
185 conversion from signed to unsigned). Don't use SCM_ASSERT for
186 range checks.
187
188 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
189 scm_bit_count_star): Use scm_out_of_range to signal range
190 errors.
191
192 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
193 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
194 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
195

DH		 1962000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
197
198 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
199 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
200 Perform all range checks based on the input value. The former way
201 of using the value that is assigned to the target variable fails
202 if the assignment to the target variable itself can change the
203 value because of type conversion.
204
205 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
206

MD		 2072000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
208
209 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
210 doesn't yield any new cells. In theory this could happen if all
211 cells allocated with NEWCELL are either in use or conservatively
212 marked and all cluster spine cells are conservatively marked.
213 (Thanks to Dirk.)

218
219 * error.c (scm_wta): Removed sick dispatch code for memory
220 errors. (More sick dispatches still to be removed.)
221
222 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
223 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
224 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
225 (scm_vector_set_length_x): Now using scm_memory_error to signal
226 memory errors.

233 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
234 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.

DH		 2382000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
239
240 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
241 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
242 appropriate error signalling function.

ML		 2522000-06-28 Michael Livshin <mlivshin@bigfoot.com>
253
254 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
255 allocate instead.

DH		 2572000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
258

260 Moved to gc.c.
261
262 (scm_init_async): Moved initialization for scm_gc_async and
263 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
264 from gc.c.
265
266 * async.h (scm_gc_async): Not globally visible any more.
267
268 * gc.c (scm_gc_stats): Made callable even from within regions
269 where gc is blocked.
270
271 (scm_gc_end): Eliminate the hardcoding of the marking of the
272 scm_gc_async from the gc core.
273
274 (scm_init_storage): Don't initialize the scm_asyncs list here.
275 This is now done in asyncs.c.
276
277 (scm_gc_vcell): Moved here from async.c.
278
279 (gc_async): Renamed from scm_gc_async, moved here from async.c
280 and made static.
281
282 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
283 here from async.c.
284
285 (mark_gc_async): New hook function for scm_after_gc_c_hook.
286
287 (scm_init_gc): Added initialization of scm_gc_vcell and
288 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
289
290 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
291 initialized.

296 to unprotect struct types with no instances.

DH		 3002000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>

ML		 3052000-06-21 Michael Livshin <mlivshin@bigfoot.com>
306
307 * guile-doc-snarf.in: use cut instead of sed, that's much much
308 faster. also, don't call basename more than needed. and, to gain
309 a couple of microseconds more, don't call cat needlessly. (thanks
310 to Brad Knotwell).

315 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
316 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.

319
320 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
321 #include "libguile/fluids.h".
322
323 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
324 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
325
326 * root.h (scm_top_level_lookup_closure_var,
327 scm_system_transformer): Removed. (It's no sense in having the
328 *variable* be a "fluid".)
329
330 * root.c (mark_root): Removed marking of
331 s->top_level_lookup_closure_var and s->system_transformer.
332

336
337 * gc.h, tags.h: Be kind to compilers which must see hash signs in
338 column 0. (Thanks to Ian Grant.)
339
340 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
341 the long_long type. (Thanks to Bernard Urban.)

346 scm_default_min_yield_1, scm_default_init_heap_size_2,
347 scm_default_min_yield_2, scm_default_max_segment_size): New global
348 variables. Can be customized by the application before booting
349 Guile. (We might want to be able to control these parameters
350 dynamically through the "options interface" in the future, but
351 note that that is additional functionality. Here we're giving
352 default values which the environment variables can override.)
353
354 * list.c (scm_cons_star): Updated comment.
355
356 * smob.h: Changed comments for scm_make_smob_type and
357 scm_make_smob_type_mfpe, warning that the latter might be
358 deprecated in a future release.

379 * gdbint.c (gdb_print): Print warning instead of calling scm_write
380 if Guile isn't yet initialized.
381
382 * print.c (scm_current_pstate, scm_make_print_state): Simplified
383 tests, using the assumption that Guile has been initialized.

425 size_t.
426 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
427 Ditto for `tmp_size'.

429
430 * random.c: #include <string.h>. (Needed by memcpy.)
431
97ebbbca
MD		 432 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
433 indicating stdin, instead of "" and don't reset ARGC. This is a
434 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
435 it is correct, and perhaps even better.

493
9c8dca4e
MD		 494 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
495 shouldn't use Make rules which aren't supported by most Make
496 programs.)
d230c130
MD		 497 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
498 want these dependencies recorded, since they would get bogus
499 relative paths; libguile.h is only used in gh.h and guile.c.)
9c8dca4e
MD		 500 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.

535
536 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
537 write it to the temp file first and check the CPP return code.
538 (I introduced this bug earlier, and this probably caused people
539 with non-GNU C preprocessors to get empty *.x files and not to
540 have the build fail right away...).
541
542 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
543 -- at least my libc5-based Linux system doesn't define SIGSYS.

599 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
600 (Thanks to Keisuke Nishida.)
601
2c4fc472
MD		 602 The major reason for Guile's slow loading speed has been the fact
603 that a chain of Scheme level procedures has been evaluated for
604 every top-level symbol lookup during the first pass through the
605 code.
606
607 The following is a kludge which I suggested four years ago, and
608 which I've repeatedly suggested since. Personally, I've never
609 been bothered by Guile's slow loading speed, so I thought I would
610 let someone else do it...
611
612 But since the new environments will be included first in
613 Guile-1.5, I thought it would make people happy to get the kludge
614 into 1.4.
615
616 * modules.c: Added #include "libguile/vectors.h";
617 Added #include "libguile/hashtab.h";
618 Added #include "libguile/struct.h";
619 Added #include "libguile/variable.h";
620 Capture Scheme level `module-make-local-var!' to be used in the
621 standard eval closure.
622 (scm_standard_eval_closure): New primitive.
623
624 * modules.h (scm_standard_eval_closure): Declare.
625
626 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
627 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
628
629 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
630 standard eval closures.
631
632 * variable.c: Code layout fixes.

644

MD		 645 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to

4ecf5aa3
MD		 651 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
652 abort ().
653 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
654 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
655 the address of these expressions since they use SCM_VALIDATE_CELL.
656 (Thanks to Bernard Urban.)
657

662
663 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
664 from GUILE-VERSION definition of LIBGUILE version. Added to
665 libpath.h definitions for guileversion and libguileversion which
666 both get their values from GUILE-VERSION definition.

677 mit-pthreads.c, mit-pthreads.h: Deleted.
678
679 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
680 references to deleted files and fsu/mit thread support in
681 general.
682

DH		 6832000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
684
685 * hooks.c (symbol_name, scm_create_hook): Restored the original
686 behaviour of scm_create_hook. Changing it was bad as Carl
687 R. Witty has pointed out.
688
689 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
690 protect the object.
691
e11f8b42
DH		 6922000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
693
694 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
695 soon not be done by scm_create_hook any longer.
696
697 * hooks.c (make_hook, print_hook, scm_create_hook,
698 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
699 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
700 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
701 longer have names. As an intermediate solution, the name
702 predicate is emulated via object properties, but use of this
703 feature is deprecated.
704
705 * hooks.h (scm_free_hook): Removed, as it is never defined.

DH		 7072000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

894a712b
DH		 709 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
710 Un-deprecated since otherwise user code can't determine whether a
711 number fits into an inum any longer. The names should be changed
712 some time, though.
713
714 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
715

723 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
724 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
725 SCM_{SET}?C[AD]R unless they are known to be cons cells.
726
727 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,

769
770 * guile-doc-snarf.in: put the preprocessed file through sed to
cf00e803
ML		 771 trim all lines to 1024 chars. I hope it doesn't break anybody's
772 sed. we'll see. (note: this is lossy trimming, i.e. the spill
773 isn't wrapped around but actually chopped off. this seemed to me
774 safe because the current snarfer doesn't understand multi-line
775 cookies anyway. in the long term, it would be nice not to depend
776 on AWK for anything.)
a564e775
ML		 777
778 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted

783
784 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
cebd4392
ML		 785 the yucky, ugly and nasty conditional compilation back. sorry,
786 but it was either that or requiring GAWK to build Guile.
787 (lots of places): removed the code that implemented the old GC
788 scheme.

ML		 789
790 * init.c (scm_boot_guile_1): removed the code conditioned on
791 !GUILE_NEW_GC_SCHEME.
792
793 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
794
795 * gc.c (scm_protect_object, scm_unprotect_object): change the
796 implementation to more efficient (at least in the time complexity
797 sense). the calls should now also be thread-safe -- I suspect
798 that people expect them to be. (thanks to Han-Wen Nienhuys)
cebd4392
ML		 799 (lots of places): removed the code that implemented the old GC
800 scheme.
686765af
ML		 801
802 * hashtab.c (scm_hash_fn_create_handle_x): add missing
cebd4392
ML		 803 SCM_REALLOW_INTS before return. I really wonder about the
804 possible interactions between hashtables, threads & GC. it
805 doesn't look healthy at all.

816 objects on the heap.

820
821 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,

851 the actual arguments in the list, but rather the rest argument as
852 a list of arguments.

1143
1144 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1145 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1146 indicate that a division has a remainder, return SCM_UNDEFINED
1147 instead. It is improbable that anyone actually used these
1148 functions outside of numbers.c. For this reason and due to the
1149 change in behaviour the functions are static now. Thus, if
1150 surprisingly there are users of these functions they will at least
1151 get alarmed.
1152

1696 * guardians.c (scm_guardian_zombify): mark all zombies in a
1697 separate loop after processing all the currently known live
1698 guardians, so as to not introduce order dependencies (thanks to
f6e2fd8b 1699 Gary Houston). note that the order problems are still there if
843e4e9d 1700 some guardians are themselves zombies, but that's a sick case that

2051
2052 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X

2066 shifting, not constant. Thanks to Dale P. Smith.
2067
2068 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2069 for being less than zero. Decode it to a C value first. Again,

DH		 20722000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2073
2074 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2075 non scheme values. If raw data is stored in SCM variables, it has
2076 to be accessed using SCM_UNPACK until a better solution is found.

2099 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2100 made SCM values into pointers. This turned an arithmetic
2101 computation of the address of the vcell into a pointer-arithmetic
2102 one, thereby screwing up marking of structs.
2103 Bugfix 2: Removed incompletely introduced loop variable `j' used
2104 when protecting the tail array of a struct.

2373 new way of allocating heap. It makes Guile fast, but still
2374 contains bugs.
2375
2376 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2377 allocating heap. The basic idea is to trigger GC every Nth
2378 allocated cell and grow heap when free list runs out. The scheme
2379 has been extended so that GC isn't triggered until all remaining
2380 cells are used. The implementation is also prepared for
2381 development in the direction of POSIX threads.
2382
2383 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2384 SCM_EXPHEAP should return half of the heap size.

2394 they exist. (This may be replaced by a Scheme level mechanism in
2395 the future.)

5ebf0091
MD		 2407 * init.c (scm_boot_guile_1): Use same initial segment size for
2408 1-word and 2-word segments. Having the smaller size causes Guile
2409 to GC too often. Obviously something needs to be done to allow
2410 for a smaller 2-word segment without this to happen. (The amount
2411 of heap for each type should be automatically adapted to the
2412 application somehow.)

2422 all of Guile basics fits into one segment and there suitable room
2423 for work.
2424 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2425 instead of 2.
2426 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2427 Freelists now contains information about object span, cells

MD		 2438 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2439 rewrite of handling of real and complex numbers.
2440 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2441 removed along with the support for floats. (Float vectors are
2442 still supported.)
2443
2444 * tags.h (scm_tcs_bignums): Removed.

2477 The following changes implement primitive support for double cells
2478 (i.e. four-word cells) and change the representation of some
2479 things to multi-cells instead of cons+malloc. (Applied and
2480 modified by mdj.)
2481
2482 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2483 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2484 multi-cell access macros (used by the ones below).
2485 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2486 macros.
2487
2488 * gc.c (scm_freelist2): multi-cell freelists.
2489 (inner_map_free_list): map_free_list, parameterized on ncells.
2490 "nn cells in segment mm" was misleading for ncells > 1; changed to
2491 "objects". still print cells too, though.
2492 (scm_map_free_list): rewritten using inner_map_free_list.
2493 (scm_check_freelist): get freelist as parameter, since now we have
2494 more than one.
2495 (scm_debug_newcell2): multi-cell variants of
2496 scm_debug_newcell.
2497 (scm_gc_for_newcell): take ncells and freelist pointer as
2498 parameters.
2499 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2500 now double cells).
2501 (scm_gc_sweep): don't free the float data, since it's not malloced
2502 anymore.
2503 (init_heap_seg): didn't understand what n_new_objects stood for,
2504 so changed to n_new_cells.
2505 (make_initial_segment): new function, makes an initial segment
2506 according to given ncells.
2507 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2508
2509 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2510 {DEFER,ALLOW}_INTS thing removed.
2511
2512 * numbers.h (struct scm_dbl): changed to represent a double cell,
2513 with the number in the second half.
16d35552
MD		 2514
2515 * dynwind.c: changed the wind-guards representation to double
2516 cell.
2517
2518 * procs.c, procs.h: changed the procedure-with-setter representation
2519 to double cell.
2520
2521 * async.c, async.h: made async representation a double cell.
2522
16d35552 2523 * dynl.c: made dynamic_obj representation a double cell.

2527 * ports.c (flush_void_port): renamed to flush_port_default.
2528 (end_input_void_port): renamed to end_input_default.
2529
2530 * init.c (scm_standard_stream_to_port): create a void port instead
2531 of opening /dev/null if the standard file descriptors are bad.
2532 advantages: no portability problems, doesn't waste a file descriptor,
2533 simplifies the code (thanks to Marius for the idea).
2534
2535 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2536
2537 * void ports: make reading from a void port give EOF instead of
2538 segv:
2539 * ports.c (s_scm_sys_make_void_port): modified docstring.
2540 (fill_input_void_port): new proc.
2541 (scm_init_ports): set up fill_input_void_port.
2542 * ports.c (scm_port_non_buffer): new proc.
2543 (scm_void_port): call scm_port_non_buffer.
2544
2545 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2546 which was incorrectly appended.

2551 that we can't use autoconf for this. Autoconf itself relies on
26fba922 2552 the existence of `sed' somewhere on your path.) (Thanks to Dirk

2581 the fdes is valid before doing anything else. check that
2582 the file descriptor supports the modes required.
2583 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2584 work: just use the default buffer size.
2585

2587 BODY: it doesn't take a jumpbuf arg.
2588
2589 * init.c (scm_standard_stream_to_port): install a handler in case
2590 scm_fdes_to_port throws an error. don't check here whether the
2591 file descriptor is valid, since scm_fdes_to_port will do that.
2592 set the revealed count depending on whether the port got the
2593 standard file descriptor.

2637 1.
2638
2639 This is a preliminary attempt at a cleanup of the threads support

2655 and scm_cond_init instead.
2656 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2657 is ANSI C, but should we check for individual error codes in
2658 configure.in?

2708 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious

GH		 28322000-01-31 Gary Houston <ghouston@arglist.com>
2833
2834 * strings.h: don't use SCM_P. don't include <string.h>.
2835 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
a00c95d9 2836
bd9e24b3
GH		 2837 * strings.c (scm_string_ref): make the 2nd argument compulsory.
2838 previously it defaulted to zero for no good reason that I can see.
2839 use a local variable for SCM_INUM (k). replace
2840 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
2841
2842 (scm_makfromstr): cosmetic changes.
2843
2844 (scm_string): Accept only chars in the list, not strings, for
2845 conformance to R5RS (particularly for list->string, which is
2846 supposed to be the inverse of string->list.) remove
2847 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
2848 scm_makstr handles the cell allocation. when reporting wrong-type
2849 arg, don't report the position as 1.
2850
2851 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.

2856
28d77376
GH		 2857 * filesys.c (scm_select, retrieve_select_type, get_element,
2858 fill_select_type, set_element): modified so that Scheme
2859 "select" tests port buffers for the ability to provide input
2860 or accept output. Previously only the underlying file descriptors
2861 were checked. Rewrote the docstring.

2869
2870 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
2871 adding "x" prefix to the line so that guile-func-name-check
2872 doesn't complain unnecessarily.

a00c95d9 2884 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
a28eb127
GB		 2885 suggests removing tag.c altogether (and using a new `class-of'
2886 instead).
2887
2888 * strings.c: Added documentation from Gregg A. Reynolds. Edited
2889 a bit by me to use FOO instead of @var{foo} and to have the
a00c95d9 2890 summary come before preconditions on input. Also dropped trailing
a28eb127
GB		 2891 (rnrs) note.
2892
2893 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
2894 function with scm_make_subr_opt w/ last arg of 0 so it is not
2895 visible at the Scheme level. Mikael says that this is the right
2896 thing because the first arg to the proc is the guts of a compiled
2897 closure and shouldn't be exposed to the Scheme level.

2979
2980 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
2981 SCM_VALIDATE_LONG_COPY
2982
2983 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
2984 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
2985 couple of formal arguments (and fix their uses) to make arguments
2986 match the documentation.

GB		 2993Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
2994

GB		 2998Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
2999
3000 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3001 the way guile-1.3.4 worked, but #if 0 out the version using
3002 SCM_VALIDATE_INUM_COPY for stricter testing.

3005
3006 * guile-doc-snarf.in: Use new $fullfilename for running
3007 guile-func-name-check, and put "$fullfilename" and "$filename" in
3008 quotes at uses to make sure re-splitting on whitespace does not
a00c95d9 3009 occur (so filenames w/ embedded whitespace would work okay, though
95aec69f
GB		 3010 I sure hope we never have to deal with that! :-) ). Thanks to
3011 Mikael for pointing out the source_dir != build_dir was broken.

GB		 3013Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3014
3015 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3016 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3017 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3018 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3019 variants.
3020
3021 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3022 then return whether it's an open port (was validating that it was
3023 an open port -- this was a bug I introduced back in December, but
3024 my careful reading of diffs caught it).
3025
3026 * numbers.c: Recombine the two conditional-compilation paths for
3027 all the log* primitives -- they were split based on #ifndef
3028 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3029 some bugs and inconsistencies in the two sets of implementations.
3030 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3031
3032 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3033 SCM_VALIDATE_INUM_COPY once where it should've been used.
3034
3035 * fluids.c (scm_internal_with_fluids): Use
3036 SCM_VALIDATE_LIST_COPYLEN.
3037
3038 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3039 this is questionable as it relaxes type safety, but other changes
3040 were useful and all SCM_NUM2LONG's should probably be
3041 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3042
3043 * evalext.c: line-break change on 1 line.
3044
3045 * eval.c (nconc2last): Takes a non-empty list as its first
3046 argument, not just a list.
3047
3048 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3049

3053 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3054 where possible.
3055
3056 * symbols.c (scm_sysintern0): Fixed the function name in a
3057 scm_misc_error invocation.
3058
3059 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3060 use scm_return_first to ward off latent GC bug that Mikael caught.
3061
3062 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3063 used before but should've been.

3072 * guile-func-name-check.in: Added this script to statically check
3073 #define FUNC_NAME, #undef FUNC_NAME in the source.
3074
3075 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3076 redundant comment, semicolon; caught by new guile-func-name-check
3077 script.
3078
3079 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3080 Caught by new guile-func-name-check-script.
3081
3082 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3083
3084 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3085 guile-func-name-check.
3086
a00c95d9 3087 * guile-doc-snarf.in: Run guile-func-name-check on the file before

3096
3097 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3098 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3099 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3100 consistency with the other macros dealing with immediate
3101 characters. (Similar to INT -> INUM change a week or so ago).

3105 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3106 net_db.c, read.c, socket.c: Update error messages to use ~A for
3107 %s, ~S for %S to work with new `simple-format' format and be
3108 standardized better.
3109
3110 * print.h, print.c (scm_simple_format): Added `simple-format'
3111 primitive. It's the old scm_display_error, with ARGS now a rest
a00c95d9 3112 parameter, and the destination first instead of last (and a couple
7965d98f
GB		 3113 new capabilities inspired by `format' -- #t as destination means
3114 current-output-port, #f means return the formatted text as a
3115 string.
3116
3117 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3118
3119 * backtrace.c (scm_display_error_message): Rewrote to use
3120 scm_simple_format() procedure.
3121
3122 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST

3126 Finally applied the libltdl patch from Thomas Tanner, with slight
3127 modifications.
3128
3129 * DYNAMIC-LINKING: Removed because it is obsolete.
3130 * dynl.c: Use ANSI prototypes.
3131 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3132 * scmconfig.h.in: Do not change, as it is automatically generated.

3139 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3140 against libltdl

3147 * These changes should make it unnecessary to call tzset from
3148 Scheme after modifying the TZ environment variable, even if the
3149 system date facilities cache the value.
3150 * stime.c (setzone, scm_localtime): added comments.
3151 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3152 (setzone): don't call tzset.
3153 (restorezone): call tzset only if HAVE_TZSET is defined.
3154 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3155 doc string to indicate that this procedure isn't likely to do
3156 anything useful.

3195

3197 report the position of the argument.
3198
a00c95d9 3199 * error.h, error.c (scm_out_of_range_pos): Added this function to

3203 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3204
3205 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3206 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3207 prefers that and I'm reasonably indifferent.
3208
3209Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3210
3211 * snarf.h: Factor out differences between C++ and non-C++ into
3212 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3213 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like

3220 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3221 snarf macro definitions.

3225 * chars.c (scm_integer_to_char): Use Greg's nice
3226 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3227 adherence to R5RS.

3236 instead of GUILE_PROC.

2cc0f8cb

3242 macro call.

3245
3246 * scm_validate.h: Remove some redundant NIMP tests.
3247
3248 * alist.c: minimize scope of the tmp variables, and initialize
3249 them when declared. The strange SCM_NIMP tests are replaced by
3250 SCM_CONSP tests that more closely reflect the intended semantics.
3251 However, we don't get a performance penalty here, because the
3252 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3253 extremely ugly use of ASRTGO macros was removed: The calls to
3254 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3255 label parameter that only exists when SCM_RECKLESS is not defined.
3256 This works, because ASRTGO itself is defined in a way that it only
3257 makes use of the label parameter if SCM_RECKLESS is not defined
3258 (shudder!). Does guile make at all use of the possibility to
3259 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3260 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3261 we now only get one test.
3262
3263 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3264 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3265 some variables in `list?'. Fix `reverse' and `reverse!'
3266 primitives to handle improper lists better.

3270 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3271 macros and SCM_DEFINE macros to match GNU coding standards.

3278
3279 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3280 better consistency with the names of other SCM_VALIDATE_ macros
3281 and better conformance to guile naming policy.

3284
3285 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3286 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3287 it's not the actual name of the formal).
1e484823
GB		 3288
3289 * guile-snarf.awk.in: Do argument/number mismatch checking and
3290 print warnings in an Emacs compile-mode parseable format.
3291
3292 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3293 SCM_OUTOFRANGE as 3rd argument.
3294
3295 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3296
3297 * __scm.h: Do not #define SCM_ARG* when snarfing;
3298 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3299 the former (using the number) requires the argument to match the
3300 formal in the current argument snarfing check.
3301
3302 * snarf.h: Give new definition of SCM_ASSERT when in
a00c95d9 3303 snarfing mode to output a lexically-identifiable sequence that the
1e484823
GB		 3304 guile-snarf.awk script uses to verify argument/position matching.
3305
3306 * ramap.c: Remove extraneous #undef FUNC_NAME.

3309
3310 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
a00c95d9 3311 current version of the same functionality; it writes the .x output
53fc4636
GB		 3312 to stdout instead of directly into the file.

3315
3316 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3317 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3318 redundant with the safer macros. Patch from Dirk Hermann applied
3319 by hand. Thanks Dirk!
3320
3321 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3322 uses in random.c.
3323
3324 * ramap.c: whitespace change.

3328 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3329 removals from Dirk Hermann.
3330
3331 * alist.c: Rename formals to match the parameter names in the
3332 documentation, updates to documentation. Thanks Dirk Hermann!
